Design and editing skills will not be useful to us, we only need a small sense of taste and the ability to translate the TOR (terms of reference) of your customers through an online translator, if they are in English (and they pay more). We will not create anything, we will just work with ready-made video templates.
First of all, we will make profiles on known freelance exchanges:
https://www.peopleperhour.com (less competition than on the first one)
It is better to use as many exchanges as possible.
After that, you need to find popular sellers in the niche of video design and editing: Creating intros (splash screens).
In their profiles, make your own unique portfolio in their likeness, with an identical description and ads.
Then you are transferred to iNvideo service and during the first 7 test days for free, you can use a huge number of templates (more than 4 thousand pieces), which you can edit.
It's better to find a client first, and then to start using the service (so that the trial period will be over before the time). You can fill your portfolio with various works for American services, borrow videos from Russian masters and vice versa, so they don't overlap. For the first time this will be enough, and then your work on TK.
Start to rock zero profiles is not easy, so take the price for volume, do more work, and then the first customers will give you good feedback. Also promote your services through your Facebook groups, saying that you are working through the exchange, that you need reviews, and are willing to do double volume for the same price as others, but for a review. You can also connect your social networks and show your work from the inside, you can stream in parallel.
